Intelligent storage device to execute a hint search

A method on a storage device for enabling a host to search for data stored across channels on a memory device without reading user data stored on the channels, the storage device comprises a controller to execute the method comprising:

• generating hash data including hint data during storage of user data on user channels in a stripe on the memory device;
• receiving a hint from the host;
• generating a request and submitting the request to a pattern search engine;
• and
• sending a hint response including flash translation indices to the host, based on a response from the pattern search engine,
• wherein the host reads the flash translation indices to request data stored at a specific location in the user channels.

A method on a storage device for generating hash data associated with user data stored on user channels to enable a host to search for data stored across channels on a memory device without reading user data stored on the channels, the storage device comprises a controller to execute the method comprising:

• receiving data sent from the host to be saved on the user channels on the memory device;
• triggering a parity generator to generate parity data for the user data;
• triggering a hash generator to generate hash data for the user data;
• storing the user data on the user channels, the parity data on a parity channel, and the hash data on a hash channel;
• receiving a hint from the host;
• searching the hash channel for the hash data that matches the hint;
• and
• sending a hint response including flash translation indices to the host,
• wherein the host reads the flash translation indices to request data stored at a specific location in the user channels.
